I've run tests with both patches applied. I haven't tried with the
latest HOT-versions, but they should in theory work fine together.
You'll get a conflict on the pg_stats-views, both patches add
statistics, but IIRC you can just ignore that and it works. I think
there's a conflict in regression tests as well.
Give it a shot and let me know if there's problems :).
Heikki, the signature of heap_fetch is changed slightly (we pass
a boolean to guide HOT-chain following) with HOT. That might
cause a conflict, I haven't tested though.
Grzegorz, if you can try HOT as well, that will be great.
Thanks,
Pavan
